2 Claims.

This invention relates to improvements in metallic coating recovering devices.

The principal object of the invention is to produce a device WhlCh will recover shutting down for any appreciable length of time.

Other objects and advantages will be apparent during the coarse of the following description.

In the accompanying drawing forming a part are employed to designate like parts throughout the same,

ruin a. large amount of material even sifting through cracks in doors and being side rooms, so that some of the losses have been formed a series of outlet pipes I. To these outlet pipes 1, fabric sleeves 8 are secured. Positioned beneath the drum 6 and spaced therefrom REOOVERING DEVICE San Francisco, Calif. 1935, Serial No. 17,587 (01. 18370) is a funnel-shaped member 9, having an upper surface I I, which carries pipes l2 ing with the interior of the funnel.

the fabric sleeves 8 may have their lower ends connected to the pipes I2. Secured to the bottom of the funnel is a receptacle l3 to receive the recovered material. A vent or breather pipe I 4 extends through the drum 6 and into the funnel 9, its lower end extending into the funnel a concarpet material. Surextending between the the funnel 9 is a covrounding the device and drum 6 and upper end of ering l8, also made of the blanket I! and having its the center of the device.

circular motion so that the material within the drum 6 is kept agitated and as the only means for escape of the air is down the pipes 7 it is apparent that the laden air will take this course. As soon as the air engages the sleeves 8 some of the air will pass through the sleeves, thus deby gravity into the funnel the container l3. Any excess air will escape through the pipe l4 and screen capes free of any dust content. The screen I6 is merely for the purpose of preventing any eddy currents being set up by drafts blowing down or across the end of the pipe l4. It is obvious that due to the fineness of this dust, some small phere were it not for the blanket I1 and cover- The pile of the covering and blanket It will thus be seen that I have produced a device which will accomplish the objects above set forth.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:--

1. In a device of the character described, a drum adapted to receive dust laden air, pipes extending downwardly from said drum, a funnelshaped container pos'tioned beneath said drum and spaced therefrom, the upper surface of said funnel-shaped member being closed and having pipes extending therefrom and communicating with the interior of said funnel, fabric sleeves extending between the pipes of said drum and funnel, a blanket supported on the closed end of said funnel, said blanket having an upstanding pile, and a breather pipe extending into said funnel and extending to a point above the top of said drum.

2. In a device of the character described, a drum adapted to receive dust laden air, pipes extending downwardly from said drum, a funnelshaped container positioned beneath said drum and spaced therefrom, the upper surface of said funnel-shaped member being closed and having pipes extending therefrom and communicating with the interior of said funnel, fabric sleeves extending between the pipes of said drum and funnel, a blanket supported on the closed end of said funnel, said blanket having an upstanding said funnel and extending drum, and a covering surrounding said device and extending between said drum and said funnel, said covering having pile formed upon its inner surface.
